' FUR/RING- AND FASTENING DEVICE.

Application filed. January 16, 1925.- Srial No. 81,639.

such projection and the spacer after thedevice has been driven intoposition.

An object of the invention is to provide the device with a spacingmember which will not spread or flatten on wall when force-dthereagainst and thus insures a uniform and predetermined spacing of thenetting from the wall. w

Another object is to provide the device with a spacing memberwvhichwillhave a bearing surface of maximum area and.

smoothness wherebymutilation of the surface to which itisapplied may beprevented.

A further object of the invention is to provide a device of thecharacter described with which plaster will readily become keyed whenapplied thereover.

A still further object of the invention is to provide the dev ce with aspacing member which will interfere to a minimum eX- tent with thedirect keying of the plaster to the netting. v

The invention possesses other objects and features of advantage, some ofwhich, with the foregoing, will be set forth in the followingdescription of the preferred form of my invention which is illustratedin the drawings accompanying and 'lTOl'D'lll'Ig part of thespecification. It s to be understood that I do not limit myself to theshowing made by the said drawin s and description,

as I may adopt variations of the preferred, form within the scope of myinvention as set forth in the claim.

Referring to said drawings:

Figure 1 is a perspective view of one em.- bodiment of the device of myinvention.

Figure 2 is a plan view of a blank used in forming the spacing member ofthe device shown in Figure 1.

Figure 3 is a fragmentary sectional view of a wall showing devicesoperatively positioned thereon both before and after being driven tofinal position.

with one face 17 resting thereagainst.

Figure 4 is a perspective view of another embodimentof the device.

The operative application of most of the heretofore used devices of theclass to which the present invention relates has presented certaindifiiculties which have prevented a more wide-spread use of suchdevices. Thus,

it ,is desirable and customary to drive the.

l'a teners to place with a single blow of a heavy hammer, but most ofthe before mentioned devices, if the hammer blow be the least bitexcessive, have tended to flatten out or to be driven into the sheathingso that the netting has either been spaced too close,

to the wall or is unevenlyspaced therefrom, thus making difiicult theplacing of a plaster coat on the netting such as will have auniformthicknessand smooth exterior surface. On the other hand, thefasteners having spacing portions so formed that they cannot beflattened or driven into the wall, have usually prevented the keying ofthe plaster to the netting immediately adjacent their point of contactwith the netting. In accordance with the present invention, however, afastener spacing member is provided which will neither'be flattened outor driven into a wall and, which will at the same time present a minimumportion thereof against the net-ting.

The embodiment of my invention shown in Figures 1 to 3 inclusivecomprises a fastening unit 7having a nail portion 8 provided with apoint 9 at one end and a wire engaging head 11 at the other end( As hereshown, the head His of circular form and is relatively large so that itmay engage one or more strands of a wire netting 12 between itself and asuitable spacing or fur-ring mem-' her.

Since, as previously pointed out, it is esirable that the spacing memberpresent a 7 large base to the'sheathing 13 and have a comparativelysmall contact with the net- 14 is formed as though of a piece of tubingof triangular section placed with its axis parallel to the surface 16 ofthe'wall and The face 17, it will'be noted, is provided with aperforation 19 arranged to receive the shank 18 of the nail 8 which also)asses through a suitable opening 21 provic ed at the top edge or corner22 of the member 1a and against which the netting 12 is arranged to beheld seated by the nail head 11.

As here shown, the member 1 1 is of unitary structure and is formed by asuitable bending to shape, of a blank 23 having parallel end edges 24fand 26. It will be noted that tac perforation 19 is provided in thecenter portion of the blank which forms the face 17, and that the edges24 and 26 are each provided with segmental perforations, so that whenthe shank is positioned in the perforation 19 and the end portions 27and 28 of the blank have been bent from the edges of the vportion 7 tobring the outer edges there-of into juxtaposb tion, the opening 21 willbe defined about the nail shank by the segmental. perforations and theedges 24 and 26 will together define the spacing member bearing edge orcorner 22. To insure against undue relative movement of the edges 24 and26 before and during the positioning of the fastener, the portion 27 ispreferably provided with tabs 29 which may be bent down over the edge ofthe portion 28 as hereinshown, but it will be particularly noted thatwhen the nail head is in position to hold the netting tioned and heldnear the nail point when the fastener unit is assembled, handling of thefastener as a unit thus being made possible. It will also be noted thatthe tabs 29 project above the corner 22 and are preferably sospacedapart that the nail head when driven against the spacer will bearthereagainst to thereby imprison the netting between itself and theedges 24': and 26 without undue pressure on the netting strands.

In the embodiment shown in Figm'e 4, it will be noted that the upper'nail'opening 21 is rectangular rather than circular, so that the nailmay, if desired, be angularly disposed with respect to the'top edge 22.In this i'nanner, the nail may be primarily in.-

serted to slant toward a portion of wire to be stretched and thenstraightened up as,'or before, it is driven, to thereby stretch thewire.

I claim in a device of the character described a spacing membercomprising a triangular tube formed of a strip of sheet metal with theends recessed and abutting at one of the corners, a fastener comprisinga pointed and headed shank passing through the said spacer recesses andthe side opposite said end of the shank whereby it may lie against thewall when the device is operatively disposed, and .means incorporatedwith the spacer for holding the strip ends together. In testimonywhereof, I have hereunto set my hand at Oakland, California, this 12thday of January, 1926. I
